Title: Fet gate drive circuit
Inventor: NARA AKINOBU
IPC: H03K17/04
Filed: 1994-04-05
Abstract: PURPOSE:To drive at a high speed a switching circuit which uses an FET of large gate input capacity. CONSTITUTION:The DC voltage is charged to a capacitor 19 from a high frequency source 25 via an insulating transformer 23 and a diode 21. Both FET 13 and 17 are turned off with an FET 15 turned on respectively when 8 drive signal source 1 generates the positive voltage. Meanwhile an FET 29 is turned on and driven by the secondary winding voltage or a driving transformer 3 via a diode 9 and a resistor 11. When the polarity of the source 1 becomes negative, the FET 15 is turned off with the FET 13 and 17 turned on respectively. Under such conditions, the secondary winding voltage of the transformer 3 is cut off and the charging voltage of the capacitor 19 is applied to a circuit. Thus a a transistor TR 11 is turned on and set in an adverse bias state after rapidly passing the zero state or tune gate voltage by the charging voltage applied between the gate and the source or the FET 29 which is turned on. The backward bias voltage can be undependently set at the proper value.

Filed: 1992-04-10
Abstract: PURPOSE:To provide a conductive thin film having uniform quality and excellent electric and mechanical characteristics by forming a plurality of thin films of different materials in solid phase as layers on a base. CONSTITUTION:Target modules 1a are arranged by a predetermined number at a predetermined angle of inclination to the direction in which a target unit 3 travels. Mo and Ta are used as targets 2. An applied power control portion 8 controls a voltage applied to each target 2. The control portion 8 also sets the rate of accumulation. The rotating speed of a rest 5 is controlled by a rotating mechanism portion 7. A target cell 4 is heated and spattered to form films comprising Mo layers M1-M3 and Ta layers T1-T3 alternately laid on the base S of the target cell 4. The films are then annealed so that the Mo and Ta of each layer are mutually dispersed and form a solid phase. Al-Cr, Al-Pd, Al-Ta and the like are usable as metals.

IPC: G06F17/21
Filed: 1992-04-10
Abstract: PURPOSE:To obtain an information processor in which cursor moving operation can be executed with a sense of security by providing a dummy line feed code deleting means to delete a dummy line feed code when cursor movement data is inputted. CONSTITUTION:A cursor is positioned at a position next to the end of a sentence, and a sentence end code is attached to the position of the cursor. In this case, when a cursor lowering key is pushed, the cursor is moved downward by one line, and the sentence end code is attached to the next (right) of a character code '3' and the head of the line below it. When a cursor raising key is pushed, the cursor is moved upward by one line, and the dummy line feed code is deleted. Then, the sentence end code is attached to the next (position of cursor) of the character code '3' of the actual sentence end. Accordingly, there is no need to execute troublesome operation such as to delete the unnecessary line feed code, and a user can execute the cursor moving operation with a sense of security without being conscious that he must delete the unnecessary line feed code.

IPC: H01F7/02
Filed: 1979-07-20
Abstract: PURPOSE:To improve the efficiency of working for containing magnets between synthetic resin sheets and to prevent the magnets from moving therebetween by containing magnetic pieces not yet magnetized and provided at a suitable interval between synthetic resin sheets, adhering the sheets and then magnetizing the magnetic pieces. CONSTITUTION:Heat shrinkable synthetic resin sheets 1, 1' are used, recesses 2 are formed at suitable interval on the sheet 1, magnetic pieces 3 not yet magnetized are contained in the recesses 2, and are sealed with the sheet 1'. Then, the magnetic pieces 3 are magnetized to produce magnets 3'. The configuration is effective by forming the recesses 2 slightly larger than the magnetic pieces to increase the stability of the magnets 3' and thermally shrinking the sheets 1, 1'. The sealed sheets are cut in a necessary size, and are mounted in an adequate state at a necessary position. Since this configuration contains the magnetic pieces not yet magnetized disposed between the sheets, it improves the efficiency of working for containing the magnetic pieces. Inasmuch as the magnets are not moved therebetween, the sheets can be easily stitched, and produces no rust at the magnets.

Further the motion control means 43 of this robot 1 waits for the start of a motion until it receives the motion admit signal 56. Another robot 2 operates in a similar way. Thereto a plurality of interference check changeover signals 58, 59 are added, and when the interference check changeover signals are put off by the working procedure control means 41, 42. the interference check is disengaged temporarily. That is, the robots 1, 2 are left operating whether they might interfere with each other or not.

Abstract: PURPOSE: To suppress the natural elution from a zinc electrode, to improve the use efficiency of this zinc electrode and to save labor for taking out of the zinc electrode, etc., by energizing an insoluble electrode disposed in a plating bath as anode and the zinc electrode at the time of plating work as cathode when stopping the plating work. CONSTITUTION: DC current is supplied with the zinc electrode 2 in the alkaline plating bath 1 as the anode and a work 3 as the cathode to allow zinc ions to flow out of the zinc electrode 2 and to form a zinc film on the work 3 surface during the plating work. A switch 5 of the circuit is turned off and is changed over to a switch 8 to form a circuit with the insoluble electrode 6 held immersed in the plating bath 1 and to feed the DC current with the insoluble electrode 6 as the anode and the zinc electrode 2 as the cathode at the time of stopping or pausing the plating work. The current density of this case suffices with about several to several 10mA/dm<2> . As a result, the elution of the zinc from the zinc electrode 2 to the plating bath is prevented, and moreover, the control of the concn. of the zinc ions in the bath is made possible at need.

Abstract: PURPOSE:To improve the extent of heat transfer performance by forming an evaporating part, a condensing part existing in a heat-transferred part, a hot water pipe, a working fluid stored in a gap with an inner wall of the evaporating part and a core body installed in the hot water pipe, respectively. CONSTITUTION:A core body 10 consisting of a round bar is installed in the longitudinal direction of a hot water pipe 4, reducing a passage sectional area in this pipe 4, and thereby a flow velocity of hot water is enhanced. Next, hot water is passed through the inner part of the pipe 4, and this hot water passes through an interval between an outer wall of the core body 10 and an inner wall of the pipe 4, whereby a heating value inherent in the hot water is transferred to a wall of the pipe 4 without any wastage, thus a working fluid 5 is heated. Next, a flow velocity of hot water comes high, and a rate of heat transfer to the wall of the pipe 4 becomes increased so that a melting process of snow and ice lain in and around a condensing part 2 is efficiently performed. With this constitution, the extent of heat transfer performance is thus improvable.
